Definitions
- the invention relates to a fastening system with a profile.
- Such fastening profiles serve, for example, to connect a fitting part, which may be the part of a band for connecting, for example, a door leaf with a frame, to a profile.
- a disadvantage of known fastening systems is that they are often undesirably simple to install and / or do not bring about a desirably strong attachment of the fastening piece to the profile and / or are expensive to manufacture.
- the invention has set itself the task of creating a fastening system which is improved, at least with regard to one of the disadvantages mentioned.
- the fastening system has a profile. And there is a fixing piece provided, as well as at least two clamping pieces.
- the fastening system also comprises at least two fastening means, each acting in a direction of force, which interact with the clamping pieces.

- an elastic member which acts on the clamping pieces. The system is used to attach the attachment piece to the profile.
- the attachment piece may be a band part. In one embodiment, it is not a band part. In a conceivable embodiment, it is a non-attachment for a band fitting part.
- the fastening system comprises exactly one elastic element.
- the elastic element acts on both clamping pieces.
- the fastening means advantageously each comprise a fastening screw or are formed by a fastening screw. It is also conceivable that the fastening means comprise a rivet, such as blind rivet, or are respectively formed thereby. Exactly one fastening means preferably cooperates with exactly one clamping piece. Each clamping piece preferably has a threaded hole for this purpose.
- the effect of the elastic element on the clamping pieces can be mediated by another element or other elements, such as the one or more fastening means.

- the elastic element pulls the clamping pieces together elastically.
- the second abutment surfaces comprise inclined guide surfaces for the clamping pieces.
- the guide surfaces are advantageously inclined so that they are not parallel and preferably not perpendicular to the direction of force of the fastening means.
- the distance of the guide surfaces - in the assembled state of the system - increases with increasing depth into the profile in each case to the fastening means, which cooperates with the clamping piece, for which the guide surfaces provide a contact surface.
- the guide surfaces can be flat or curved. If they are curved, they are preferably convex.
- force direction of the fastening means in the context of this document refers in particular to the direction of the main force caused by these fastening means, preferably in the fully assembled state of the system In the case of fastening screws, this refers in particular to the direction of its axis on the fastening piece In the assembled state of the system, the direction of the force preferably runs perpendicular to the imaginary plane in which the opening of the groove of the profile lies.

- the oblique mating surface may include or be formed by teeth, such as splines.
- the elastic element is designed such that it causes the positioning of the clamping pieces to each other in a mounting position, then the system can be particularly easy to assemble. Because the elastic element can relieve the mechanic of the task in this embodiment to keep the clamping pieces, such as during assembly of the attachment piece with the profile in a mounting position.
- the elastic element allows the displacement of the clamping pieces in a holding position, then again a prerequisite for a particularly easy to install the system is created. For in this case the installer does not have to remove the elastic element, for example after the attachment piece has been assembled with the profile.
- the elastic element preferably allows the displacement of the clamping pieces during the fastening of the fastening means in a holding position.
- clamping position of the clamping pieces in the context of this document in particular the position of the clamping pieces - preferably to each other - in the uninstalled state referred to, which allows the assembly of the attachment piece with the profile and / or facilitates.
- holding position of the clamping pieces means, in particular, the position of the clamping pieces which they occupy in the completely assembled state of the fastening system.
- the two clamping pieces are arranged next to one another in this groove in the mounted state of the system. These two clamping pieces are preferably not arranged in the assembled state next to one another in the longitudinal direction of the profile, but perpendicular thereto.
- the distance between the two clamping pieces in the mounting position relative to one another is preferably smaller than the width of the opening of the groove, so that these clamping pieces can advantageously be inserted into the groove with ease in the mounting direction of the assembly of clamping piece and profile.
- the distance of at least portions of two adjacent juxtaposed in the groove clamping pieces in their holding position is advantageously larger than the width of the opening of the groove. In this way, an interaction between the clamping pieces located in their holding position and the groove, such as a rear grip, is preferably possible.
- the second contact surfaces are formed so that with their help, the displacement of the clamping pieces from a mounting position into a holding position by attaching the fastening means is effected.
- this displacement can be effected exclusively by fastening the fastening means.
- the distance between the clamping pieces to each other changes in this shift, preferably it increases.
- tilting of the clamping pieces advantageously takes place, preferably in such a way that the distance of the regions of the clamping pieces further from the fastening piece increases more than the spacing between the regions of the clamping pieces arranged closer to the fastening piece.

In this way, a condition can be created that the clamping pieces - with advantage in their holding position - each cause spreading forces between a first contact surface and a second contact surface.
- the spreading force can - especially in the embodiment in which the wedge shape of the clamping pieces is wholly or partially effected by the teeth - be effected exclusively or partially by the teeth.
- a frictional connection can be effected between the clamping pieces and the first contact surfaces and preferably between the clamping pieces and the second contact surfaces.

- portions of the first abutment surfaces extend parallel to the direction of force of the attachment means, or the first abutment surfaces extend completely parallel to the direction of force of the attachment means. It has been found that even with such contact surfaces, a fixation of the clamping pieces in the direction of the force direction of the fastening means is effected. In principle, it is conceivable that regions of the second contact surfaces extend parallel to the direction of force of the fastening means, or the second contact surfaces run completely parallel to the direction of force of the fastening means.
- the attachment piece has at least one projection which engages behind a contact surface of the profile running parallel to the force direction of the attachment means. The projection also advantageously extends parallel to the direction of force of the fastener.
- the attachment piece thus engages behind the profile areas providing these surfaces.
- spreading forces of the clamping piece can be supported and / or pinching of these areas of the profile between the clamping piece and the projection of the fastening piece can be effected.
